摘　　要：以辽河油田稠油热采区块锦25为研究对象,借助地理信息系统软件IDRISI中的地统计模块,对研究区4种热采参数进行空间变异性研究,了解其空间分布特征。通过空间结构分析计算得到4种影响因子的适宜性图像,综合考虑4种影响因子的权重,利用权重线性组合(WLC)法,对油气开发风险进行评价。结果分析表明,4种热采参数存在明显的空间变异性;高危险区域位于锦25区块的中部和西部,应采取有效措施来降低这些区域的安全风险。This paper introduces a case study of heavy oil thermal recovery in J25 block of Liaohe Oilfield,based on the geostatistical module of GIS software in IDRISI and conducts research on the spatial variability of four kinds of thermal recovery parameters in the research area to understand its spatial distribution. Through the structure analysis,risk image of each influence factor is obtained and considering the four kinds of factor weights,risk of oil production is calculated and estimated with weight linear combination method. The results show that there exists obvious spatial variability in four factors,high- risk areas are located in the central and western and more effective measures are needed to reduce the risk.
